Title: A control means for a constant-speed, variable-pitch propellor driven by an internal-combustion turbine unit
IPC: B64C11/30
Filed: 1946-02-28
Abstract: 603,487. Variable-pitch propellers. ARMSTRONG SIDDELEY MOTORS, Ltd., LINDSEY, W. H., and SLATTER, B. H. Feb. 28, 1946, No. 6216. [Class 114] In a constant speed, variable pitch propeller an over-ride device is automatically brought into operation to move the blades to the feathering position when the power unit stops, and means are provided by which the over-ride is automatically put out of action when an attempt is made to start the power unit by " wind-milling," and by which the override is automatically restored when the speed rises to that at which the unit should be selfoperating. When the power unit stops a governor 23 allows a spring 22 to force a valve 19 to the left, thereby allowing motive fluid from a pipe 12 to flow into the left-hand end of a cylinder 16 to operate a plunger 15 which moves the propeller blades 13 to the minimum pitch position. The resultant change of torque acting on a torque meter 39 closes a switch 37 to complete an electrical circuit for actuating a solenoid 35 controlling a valve 34 which allows motive fluid to be applied from pipe 31 to the spring-loaded plunger 28 of the over-ride device. The plunger moves the valve 19 to the right, allowing fluid into the right-hand end of cylinder 16, thereby moving the blades to the feathering position. The circuit may also be completed by the pilot closing the fuel isolator valve 36. To start the power unit by windmilling, ignition switch 46 of the power unit is closed, the governor controlled switch 47 being already closed. A solenoid 45 then opens a switch 44 and breaks the circuit to the solenoid 35 so that the valve 34 closes to cut-off the supply of fluid to the over-ride plunger. The spring 22 is thus able to move the valve 19 to the left with the result that the blades are moved from the feathered position to cause " wind-milling ". If at a predetermined speed the unit does not then become self-operating, its governor will open the switch 47 causing switch 44 to close to complete the circuit to the solenoid 35. The valve 34 will be raised to bring the over-ride into operation, causing plunger 28 to move valve 19 so that the propeller blades are moved to the feathered position.

Title: Improved timing device for articles moving upon conveyors
IPC: B65G47/29
Filed: 1940-04-09
Abstract: 540,251. Delivering articles from conveyers. ABBEY, A. (Crown Cork & Seal Co., Inc.). April 9, 1940, No. 6427. [Class 78 (i)] Articles on conveyers are delivered singly in succession in timed relation with the movement of a machine by linkage-mechanism. As shown applied to the delivery of bottles to a filling- machine, the line of bottles on the conveyer 10 is checked by the arm 16 before the bottles are received one at a time into the pockets of the rotating wheel 11 which feeds the filling machine 12. As a pocket of the wheel 11 approaches registration with the conveyer, a cam 20 on the wheel shaft rotates the lever 18 clockwise and removes the stop 38 from the path of the pivoted pawl 31. This releases the lever 16 which then is rotated counter-clockwise out of the way by the pressure of the leading bottle of the row. On the bottle entering the pocket and being moved on towards the filling machine, the cam releases the member 18 which thereupon is restored by a spring until it abuts the stop 41. Meanwhile a second spring restores the member 16 as soon as it is released by the bottle, until it abuts the stop 27; the parts then being in position for receiving the next bottle.

Patent GB-833563-A (GB)
Title: Improvements in or relating to the preparation of chromic oxide
IPC: C01G37/02
Filed: 1957-02-26
Abstract: Chromic oxide is prepared by reacting chromates or dichromates, particularly of the alkali metals, with alumina and/or aluminium phosphate under reducing conditions at temperatures of not less than 1000 DEG  F.  The alumina or aluminium phosphate may be partially hydrated.  Reduction may be effected by means of hydrogen or carbon monoxide, or hydrocarbons or with alcohols which thereby become oxidized to aldehydes or ketones.  Inert gases such as nitrogen may be employed as diluents.  Solid reducing agents may also be employed. The reaction product is leached with water which removes the sodium aluminate or aluminium phosphate formed, to leave the product chromic oxide. Alumina is recovered from the leach solution, by carbonating to precipitate alumina trihydrate, or alternatively if the residual solution contained trisodium phosphate and sodium aluminate, the aluminium is precipitated as phosphate on carbonation and the sodium aluminate is converted to sodium carbonate.  Carbonation at elevated temperatures is preferred.  A cyclic process is shown in the Figure, where a chromium ore is subjected to alkaline roasting in the presence of recycled sodium carbonate and the sodium chromate so obtained after crystallization is mixed with recycled alumina.  The mixture after drying is reduced with carbon monoxide to <FORM:0833563/III/1> produce chromic oxide and sodium aluminate which is removed by leaching with recycled sodium hydroxide.  The chromic oxide product remaining is withdrawn and the sodium hydroxide/aluminate solution is carbonated to produce sodium carbonate solution and alumina, the latter being recycled to the reduction step.  The sodium bicarbonate is in part evaporated and recycled to the initial alkaline roast of the ore and in part converted to caustic soda which is employed to leach the reaction product from the reduction stage.

Filed: 1920-12-15
Abstract: 179,125. Venzlaff, R., Mumm, W. von, and Mumm, A. von. Dec. 15, 1920. Steering.-In a vehicle propelled by groundengaging members running in longitudinal guides and alternately depressed and raised, steering is effected by inclining the guides to right or left. The guides are mounted in pairs each pair being pivoted about the centre of the vehicle, and are inclined through power means brought into opertion by the operation of the steering-wheel. The guides 127 form an inner and outer pair connected by centrally pivoted transverse members 133,134. The guides are also connected by members 159, 160, pins on which slide in slots in bell-cranks 151, 152 pivoted on fixed pins 153,. 154 and operated by links 149, 150 connected to a pin 141. The pin 141 rides in a pair of sectorshaped pivoted slotted members 145 constantly reciprocated by a link 161 from the driving-gear 130. The position of the pin 141 in the slots 143 is controlled by a T-shaped slotted member 139 which can be adjusted transversely by rack and pinion from the steering-wheel 135. The pin 141 is normally held in the mid position in the slots 143, on moving it to one side the bell-cranks 151, 152 are operated and the guide with the ground-engaging feet temporarily raised is swung round its pivot. The main frame 122 also swings round by the reaction of the bell-crank of the other guide against its pivot. The driving gear is arranged so that the oscillations of the bellcranks synchronize with the depression and elevation of the feet. In a modification the bell-cranks are pivoted to one of the guides and engage the other by a pin and slot.

Title: Improvements relating to the interruption of electric circuits
IPC: H01H33/16
Filed: 1923-03-12
Abstract: 195,066. Chilowsky, C. March 16, 1922, [Convention date]. Sparking, preventing in the interruption of heavy currents is achieved by first introducing into the circuit an electrolytic cell the anode ot which is of aluminium, or an alloy of aluminium, the cathode of any conductor and the electrolyte an acid or a salt. The passage of the current causes the deposit of a resisting coating on the anode thereby reducing the current, which may be successively reduced in stages by the opening automatically or by hand of a succession of switches each shunted by a cell or battery of cells of progressively reduced capacity. Some of the cells may be shunted by a resistance. In the case of alternating currents both electrodes are of aluminium or aluminium alloy. In order to restore the cells to their original state after the passage of the heavy current the coating or coatings are removed by brushes or scrapers of abrasive material such as sandstone, emery, carborundum or scrapers of steel or celluloid. A cell suitable for direct current is shown in Fig. 3 in which a cylindrical vessel A constituting the anode has mounted rotatably within it a cylindrical cathode B provided with recessed and spring-pressed scrapers F which, when the cathode is rotated remove the coating from the anode. Scraper plates fixed upon one of the electrodes may be caused to bear upon the other electrode when the two are relatively rotated. The electrodes may be of conical form one of them with cutting edges so that when they are pressed into engagement with one another against the action of a spring and rotated, the coating is removed. The anode may be in the form of a disc A, Fig. 8, the lower half of which is immersed in the electrolyte and the upper part located between spring-pressed abrasive rubbers F so that, when the disc is rotated, the coating is removed. For alternating currents both electrodes may be fixed and engaged by a doubleended abrasive rubber, or rubbers may be fixed on each electrode the rubber on one electrode serving to clean the other electrode. A single container may accommodate a number of electrodes to constitute a battery of cells. In the arrangement shown in Fig. 19 both electrodes are constituted by aluminium foil which is coiled round an inner drum C<1>, where it constitutes one electrode, passes through a sleeve Z<1> on which a fixed electrode A is mounted and carried round in a circle between the electrode A and another fixed electrode B finally passing out and round a roller O<2>. To replace used electrodes the roller O<2> is revolved drawing an unused portion of foil from the inner drum.
